<td id="td_uploadFile" align="center">
                <input id="upload_A" name="upload_A" type="file" class="inputText"
                    style="width: 350px; display:none;" runat="server" />
            </td> HttpFileCollection Files = HttpContext.Current.Request.Files;
            for (int i = 0; i < Files.Count; i++)
            {                HttpPostedFile PostedFile = Files[i];
                if (PostedFile.ContentLength > 0)
                {
                    string FileName = PostedFile.FileName;
                    string AttachExt = FileName.Substring(FileName.LastIndexOf(".") + 1);
                    int TotalSize = PostedFile.ContentLength;
              }
